You will be able to have a communication port for your field bus directly connected to your RPi!
It will allow up to 32 devices to communicate through the same data line over a cable length of
up to 4,000ft with a maximum data rate of 10 Mbit/s.

GPIO Control:
8-channel Darlington driver chip (ULN2803) allowing to control electronic circuits which require more current

DIP switch to remove connection from RPi?s pin header
Directly connected on top of the Raspberry Pi using the board GPIO header pins
No wiring nor soldering is required
Duplicated the 40-pin header of the R-Pi in order to support existing expansion boards
